Transmission failure on a 2003 mercury mountaineer. The transmission failed occurred while traveling on the heavily traveled interstate 295 in nj. The failure occurred with no warning what so ever. After taking the car to multiple repair shops which included a ford dealer, I was informed that this is a common and known problem for this type of vehicles and also the ford explorer. I depend on my car to go to work and I service the car as recommended by ford. Now I am in the process of repairing the car and meanwhile I had to rent a car for a week. If I was not an alert driver, that failure could have caused an accident and serious injuries and or death to me and other motorists. I think ford should take responsibility and try to rectify the problem before someone get killed and with the very high sticker price that is associated with these kind of SUV that is supposed to be safe and reliable.

Last december the engine revved and accelerated very high, around 6,000 rpms. Afterwards, the transmission engaged, acceleration lowered and the transmission changed gears while entering a street in oncoming traffic. When attempting to accelerate the engine revved but the vehicle did not move. Attempted this 3 times to no avail. On 4th attempt the transmission engaged and the vehicle moved. The vehicle was taken to the dealer. The dealer said it was the solenoid pack and an oil additive that they believed were causing the problem. They performed the repairs. The problem recurred in june. Took the vehicle back to the dealer. The dealer found nothing on the diagnostic machine and could not duplicate the problem. The problem recurred again in july. Took the vehicle to the dealer and again the dealer could not find anything wrong. The dealer replaced the solenoid pack again because they did not know what else to do. The mechanic spoke of ongoing problems with ford mountaineers and explorers. Yesterday while on the highway this problem occurred again while attempting to accelerate. After several attempts the transmission engaged. Called ford, who referred another dealer stating there was nothing they could do. Called dealer and they offered to replace the transmission.
